This report details a 4-year-old girl with agenesis of the right third and fourth fingers, who sought consultation due to the inability to flex her seemingly unaffected second and fifth fingers. Ultrasound examination revealed substantial thinning of the flexor tendons in the second to fifth digits, with a notable absence of attachment to the middle phalanx. In addition to flexor tendon hypoplasia, hypoplasia of the third and fourth middle phalanges was observed. Hand deformities featuring both finger agenesis and flexor tendon hypoplasia across multiple fingers were exceptionally rare. In such instances, ultrasound, in conjunction with radiography, emerges as the recommended initial imaging tool for comprehensive evaluation of both the phalangeal bones and flexor tendons.<\/jats:p>","DOI":"10.3390\/diagnostics14030257","type":"journal-article","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T03:59:42Z","timestamp":1706155182000},"page":"257","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultrasonographic Diagnosis of Finger Flexor Tendon Hypoplasia in a Child with Phalangeal Agenesis"],"prefix":"10.3390","volume":"14","author":[{"given":"Cheng-I","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Chung Shan Medical University Hospital, Taichung 40201, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, School of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8243-7131","authenticated-orcid":false,"given":"Hong-Yi","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Chung Shan Medical University Hospital, Taichung 40201, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, School of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7511-9629","authenticated-orcid":false,"given":"Wei-Ting","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, Bei-Hu Branch, Taipei 10845, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, College of Medicine, National Taiwan University, Taipei 10048, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7558-5651","authenticated-orcid":false,"given":"Ke-Vin","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, Bei-Hu Branch, Taipei 10845, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, College of Medicine, National Taiwan University, Taipei 10048, Taiwan"},{"name":"Center for Regional Anesthesia and Pain Medicine, Wang-Fang Hospital, Taipei Medical University, Taipei 11600, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Levent","family":"\u00d6z\u00e7akar","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara 06100, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,25]]},"reference":[{"key":"ref_1","first-page":"965","article-title":"Common congenital hand conditions","volume":"51","author":"Chong","year":"2010","journal-title":"Singap.
